The D.A.'s Office said McNeal was the victim's ex-girlfriend, and claims she and Napolski killed him at his Newport Beach home in 1994 to collect insurance money.

"The defendant had taken out a $1 million insurance policy on the victim, as well as made allowances in his will that she would receive hundreds of thousands of dollars in the event of this death, as well as to be able to live rent free in his homes," said Farrah Emami from the Orange County District Attorney's Office.

McNeal is accused of giving Naposki a key to McLaughlin's home, where he was shot.

McNeal pleaded guilty in 1996 for stealing nearly $500,000 from
McLaughlin before and after his death. She was sentenced to one
year in jail.

McNeal at the time denied that she or Naposki were involved in
the shooting. On Wednesday, after she was put in a police squad car
and led to jail, she maintained she wasn't guilty.

Naposki was arrested in Connecticut and will face extradition
proceedings. McNeal was arrested in Orange County and is scheduled
to be arraigned Friday. Emami said she didn't know if they had
retained attorneys.

McLaughlin founded a company that developed a device that
separates plasma from blood. He had an estimated $55 million
fortune, according to court records.
